The Australian National Facility for Ocean Gliders (ANFOG) manages Slocum gliders to be deployed on the continental shelf. Ocean gliders are autonomous underwater vehicles (AUV) which harvest their propulsion from the ocean itself. By changing its buoyancy, the glider is able to descend and ascend. This momentum is converted to forward motion by its wings. Pitch adjustments are made by moving an internal mass (battery pack) and steering is done using a rudder and/or battery packs. Moving at an average horizontal velocity of 25 - 40 cm s-1 the glider navigates its way to a series of pre-programmed waypoints using GPS, internal dead reckoning and altimeter measurements. The gliders are programmed to provide data through satellite communication when it is at the surface and it is also possible to control the path of the glider during its mission. Slocum gliders, manufactured by Webb Research Corp are optimised for shallow coastal water (< 200m) where high maneuverability is needed. Slocum gliders have a maximum endurance of 30 days and are used in intensive coastal monitoring. Slocum gliders are commonly instrumented with a Seabird-CTD (SBE 41 or GPCTD), WETLabs ECO Triplet (measuring Chlorophyll-a, CDOM & Backscatter), a Satlantic OCR-504 multispectral radiometer and an Aanderaa Oxygen optode.
